The effect of melody and technique on the singing voice accuracy of trained singers.

A previous study highlighted the effect of vocal technique on the singing voice accuracy of trained singers. The intervals' precision between the notes of the tune was altered when the singers used Western operatic singing technique. In order better to understand these results, we have recorded two different melodies sung with two different vocal techniques. A large panel of trained singers (n = 50) participated in the study. The analytical method described in the reference paper has been applied. The results confirm the effect of vocal technique on the vocal accuracy of trained singers. In addition, these results provide an answer about the melodic effect and guide future work on the perception process of operatic voices.
